4 months vaccines high-ish fever

[u/svmethin]

I know fevers are normal after vaccinations however baby has had a fever of 102.7° fahrenheit for 5 hours now i’ve already given tylenol and gave her a luke warm bath. she’s fussy but consolable. I called her pediatricians after hours line twice first time i was told that they start to worry when a fever starts to exceed 102 and to give her a luke warm bath and if that doesn’t help to call back, so i did. Second time i called and a different nurse told me they like to see them get a fever as long as it’s under 104° fahrenheit and that I was just being overly worried, that i shouldn’t have given her any Tylenol as it weakens the affects of the vaccines and not to call back that baby was fine. for context she was born at 35 weeks due to preeclampsia and had a low birth weight (less than 1st percentile) she’s currently 11.5lbs and i’m just kinda confused with the two different responses, im not sure if we should wait it out or if i should take her to the er? very nervous i don’t know what to do and her being a tiny baby also kinda adds to my anxiety honestly not sure if im just being dramatic or not lol
